我厂在一台导轨磨床的工作台液压传动系统中,采用了喷咀元件作为主操纵元件,实现工作台的换向与调速。该装置已使用数年,性能良好,尚未发生故障。与一般滑阀式控制箱比较,喷咀装置具有结构简单、制造容易,体积小,重量轻等优点。实践证明,它能满足磨床液压系统传动平稳性的要求,并有一些特点可供探讨。具有喷咀元件的工作台液压传动操纵箱的结构见图1,其主要元件为一安装在心轴上,可以摆动的喷咀。动力液压油从心轴中通往喷咀,经过收敛管将静压转换为动压,
I plant a rail grinding machine table hydraulic drive system, the nozzle element used as the main control element to achieve the workbench reversing and speed control. The unit has been used for several years, performs well and has not failed. Compared with the general slide valve control box, nozzle device has the advantages of simple structure, easy manufacture, small size, light weight and so on. Practice has proved that it can meet the grinding machine hydraulic system transmission stability requirements, and has some features for discussion. Table with nozzle components hydraulic transmission control box structure shown in Figure 1, the main component is mounted on a mandrel, you can swing the nozzle. Power hydraulic oil from the mandrel to the nozzle, after convergence of the static pressure into dynamic pressure,
